JSF :: Value Input Text Cannot Bind To Bean
Feb 28, 2011
I have following bean:
public class LoginBean {
private String email;
private String password;
private SessionId sessionId;
private UserController userController;
public LoginBean() {
this.email = "";
this.password = "";
[code]....
And the jsp page is html and css and next part
<h:form id="form">
<p><h:inputText value="#{loginBean.email}" /></p>
<p><h:inputSecret value="#{loginBean.password}" /></p>
<p><h:message for="form"/></p>
<p><h:commandButton value="login" action="#{loginBean.login}" /></p>
</h:form>
I can't get the values out of the inputtext in any way?

I have an xhtml file with this content:
<h:inputText tabindex="7" styleClass="input" id="title" value="#{register.title}"
required="true">
</h:inputText>
Basically I want the user to enter his title (e.g. Mr., Dr.), which would be passed on to a bean which would send this information to me in email.
I also have a bean called register, along with setters and getters:
private String title;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
I want to pass this information to a String called body, within the bean:
body = body+"Title: "+this.title+"
";
I would then send the String in an email.

I try to bind the text-property of a selected cell of a TreeView to a label. So if the user click on a cell in the treeview the label should show the cell text. Now I am quite confused about the options I got to do so. Should I use label.textProperty().bind( ... ??? ... ) The treeview.onMouseClicked()property? or something different?

I am doing this
@Startup
@Singleton
@ConcurrencyManagement(ConcurrencyManagementType.CONTAINER)
@Lock(LockType.READ)
public class ResourceBean {
[Code] ....
And I call this singleton bean from a stateless session bean like this
@Stateless
public class ClientBean {
@EJB
ResourceBean resource;
public String create(String r)
{
String res=resource.returnString(r);
return res;
}
}
But resource.returnString(r); gives a org.apache.jasper.JasperException: java.lang.NullPointerException I started the glassfish server in debug mode and found out that "resource" was null. but @PostConstruct in singleton does print which means singleton bean exists.
Can we call singleton beans with no interface in such a way form a session bean? I actually want to acquire instance of singleton bean when a client invokes method in Client bean...

I'm new to JSP but I've to use it to grab data coming from an external site, pass data to a Bean, write data in a DB and redirect the user to another page. Follow the JSP page.
<%@page import="EJB.getResponse"%>
<%
long paymentID = Long.parseLong(request.getParameter("paymentid"));
String responsecode = "9999";
getResponse g = new getResponse();
[Code] ....
This is the bean:
@ManagedBean
@RequestScoped
public class getResponse implements Serializable {
private Long paymentId;
private String result;
private String auth;
[Code] ....
On the console I see the prints but I receive the NullPointerException
WARNING: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
at EJB.getResponse.printData(getResponse.java:72)

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

I am creating a search module page. It has many input ext field and a search button.
On my jsp, I have the following:
<label>Reference ID:
<input id="referenceID"
name="referenceID"
type="text"
value="<c:out value="${transaction.refId}" />"/>
</label>
On my servlet, I have the following (code fragment):
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Transaction transaction = new Transaction();
transaction.setRefId(request.getParameter("referenceID")== null || request.getParameter("referenceID")== "" ?null:Long.parseLong(request.getParameter("referenceID")));
request.setAttribute("transaction ", transaction );
}
Is there any alternative on executing request.getParameter on the id's of input text in order to set it on the Transaction bean so that the values will display on the user when the page reloads?

Is there an existing way to bind the content of a ListProperty? Consider the following:
private final ListProperty<Worker<?>> workers = new SimpleListProperty<>(FXCollections.observableArrayList());
public ListProperty<Worker<?>> workersProperty() {return workers;}
public ObservableList<Worker<?>> getWorkers() {return workers.get();}
public void setWorkers(ObservableList<Worker<?>> workers) {this.workers.set(workers);}
[Code]...
What I want to do is bind the content of the stateWatchedWorkers list to workers. If the entire workers list is replaced, I want stateWatchedWorkers to be updated to match the content of the new list. Put another way, I want the stateWatchedWorkers list to be mapped to the current list being held by the workers property.

I am working for my customer in a Java EE project, where we use JGoodies for binding JTable rows to text fields below the table. This works fine, but in one dialog, there are filtering check boxes. When all the check boxes - three in number - are clicked, all items become visible. If non are checked, the table remains empty. It is possible to filter out some rows, but JGoodies, which uses the table model, is not aware of this filtering. When clicking the first row in the filtered table, the first row elements of the unfiltered table are displayed in the text fields below. Is there a way to circumvent this problem?
To my opinion, the problem is not a JGoodies problem, but binding a text field with JGoodies using the table model of a table that has been filtered.
I attached an example, where I couldn't manage to bind the text field with the Bindings.bind method, but it shows the problem. I adopted some code found on the Internet for my purposes.
The table is filtered according to the combo box contents. If the GENERAL type of eating is selected, the binding of the text field below is fine. If, however, the combo box selects parts of the table contents, the text field below still gets the information from the (unfiltered) table model. Here, I need information how can I do this in the proper way.
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
/**
* A simplified mouse listener that reacts when the mouse has been clicked or pressed.
*/
public abstract class ASimpleMouseListener implements MouseListener {
/**
* Event method that is called when the mouse has been clicked or pressed.

import java.util.*;
public class kt_3_1 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

This program compiles but always returns "FUUUUUUUu", even if I'd typed "summer".

I have a popup that displays textual info and sometimes gets text input from the user. I'm using the following code:
JTextArea textArea = new JTextArea( getGameHistory( true, -2 ) );
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
textArea.setFont(new Font("courier", Font.PLAIN, 12));
scrollPane.setPreferredSize( new Dimension( 30, 100 ) );
String input = JOptionPane.showInputDialog(null, scrollPane, "Fun Chess ",
JOptionPane.YES_NO_OPTION);
This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?

Is there any way to use scanner to get input and distinguish between int and text? I'm trying to make a scanner method I can call whenever I need user input no matter if I need int or text. Using two methods (one for int, other for text) at the moment.

public class Application {
public static void main(String[] args) {
Person person1 = new Person();

I'm attempting to compare user input to a text file that I have set up whenever the user types in an employee ID number. I want to be able to tell the user that either the ID number is valid, or that it is not valid and must be re-entered by comparing it to the employee.txt file, and then record the valid ID number to the timeclock.txt file. I'm recording the next available employee ID number instead of the one I typed in. The output of the program looks like this: i82014/06/06 12:16:56 (I typed 1 as the employee ID.)
import java.text.*;

What should be the code if i want to input a different string in case of the typed string. The case is : I have a predefined string S = "Peter,please answer my question" and now when i input another string inside the text field character by character i want characters from the string S to enter instead of the input string. In short, the input string should be disguised as string S.

I need to write a program where the user inputs name, age, email, and cell and write the user inputs to a text file. I need to have it so the file can be added to if more than one set of information is added. Currently, every time I click the button, the file is overwritten instead of added to. How do I correct this? Current code is as follows:
try
{
FileWriter writer = new FileWriter("ContactInformation.txt");
BufferedWriter bw = new BufferedWriter(writer);
nameTextField.write(bw);
bw.newLine();
ageTextField.write(bw);
bw.newLine();
emailTextField.write(bw);
bw.newLine();
cellTextField.write(bw);
bw.newLine();
bw.close();
nameTextField.setText("");
ageTextField.setText("");
emailTextField.setText("");
cellTextField.setText("");
nameTextField.requestFocus();
}

Here are my codes so far , i'm having trouble with the

private JPanel pnlNumber, pnlNumber1,

The output should be the one in the picture:
Input is placed at the NUMBER text field.
Identify its factors, write it at FACTORS text field.
Determine if it is prime. If prime, output at PRIME text field is “Yes”, “No” otherwise.
